Abstract
The present invention relates to a process for the preparation of a polyurethane, comprising the process steps: i) provision of a polyisocyanate component comprising at least one polyisocyanate; ii) provision of a polyol component comprising at least one polyether polyol, one polyester polyol or a mixture of a polyether polyol and a polyester polyol, wherein the polyol component comprises a polyol ester of a polyol and a monocarboxylic acid; iii) bringing of the polyisocyanate component into contact with the polyol component to form a polyurethane.
Claims33
A process for the preparation of a polyurethane, comprising the process steps of:
- i) providing a polyisocyanate component comprising at least one polyisocyanate;
- ii) providing a polyol component selected from at least one polyether polyol, one polyester polyol, or a mixture of a polyether polyol and a polyester polyol, wherein the polyol component comprises a polyol ester of a polyol and a monocarboxylic acid;
- and
- iii) bringing of the polyisocyanate component into contact with the polyol component to form a polyurethane.
A polyol component comprising at least one polyether polyol, one polyester polyol or a mixture of a polyether polyol and a polyester polyol, comprising a polyol ester of a polyol and a monocarboxylic acid.
A process for the preparation of a polyol component comprising a polyether polyol, a polyester polyol or a mixture of a polyether polyol and a polyester polyol, in which a polyether polyol component, a polyester polyol component or a mixture of a polyether polyol component and a polyester polyol component is mixed with a polyol ester of a polyol and a monocarboxylic acid.
Use of a polyol ester of a polyol and a monocarboxylic acid as a viscosity reducer for a polyol component comprising a polyether polyol, a polyester polyol or a mixture of a polyether polyol and a polyester polyol.
